PAUL OLSSON, OF DURHAM, NORTH CAROLINA, ASSIGNOR OF ONE-HALF TO IVILLIAMT. OBRIEN, OF SAME PLACE.

GRAINING DEVICE.

SPECIFICATION forming part of Letters Patent No. 582,083, dated May 4:,1897. Application filed September 15, 1896. Serial No. 606,936. (Nomodel.)

To LtZZ whom it may concern.-

Be it known that I, PAUL OLssON, a citizen of the United States, and aresident of Durcustom to coat the surface to be grained witha suitableliquid and then by means of a cloth imitate the grain of certain woods.lhis is a very tedious and laborious operation, requiring the aid of askilled workman.

The object of my invention is to provide an improved graining instrumentwhereby the operation of graining may be performed in a rapid andefiicient manner by an unskilled person, thus materially reducing thecost.

The invention consists, essentially, of a roll composed of a flexibleelastic material, such as india-rubber, having a central apertureextending from end to end and formed on its periphery with a number ofconcentric grooves and ribs gradually increasing in size from the centerand a number of grooves and ribs at the end of the roll, as hereinafterfully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of agraining-roll constructed in accordance with my invention. Fig. 2 is asimilar view, looking from the opposite side. Fig. 3 is a cross-sectionof a modified construction. Figs. 4 and 5 are elevations of the same.

In the said drawings, the reference-n u meral 1 designates a roll ofelastic flexible material, such as india-rubber, having a centralaperture extending through the same from end to end. The periphery ofthis roll isformed with a number of concentric grooves 2 and ribs 3,which increase in size from the center till the outermost grooves meetat the opposite side of the roll from the center of such ribs andgrooves, leaving tapering spaces 4. At each end of the roll there areformed curved grooves and ribs 5 and 6, which extend inwardly toward thecenter of the roll.

In using the device the surface to be grained is first painted therequired color, and when dry the liquid graining material is appliedthereto. The roll is then drawn over the said graining material and isgiven a rotary movement at the same time, when the graining materialwill be caused to assume the appearance of natural wood.

It will be observed that the graining mate rial is not applied to theroll and then imprinted on the surface to be grained, as usual, but thewood imitations are produced by drawing the roller over the preparedsurface.

WVhile the device above described will be found very efficient in usefor the purpose of producing varying designs or patterns, Iconstruct thedevice as shown in Figs. 3, 4, and 5. In this case the pattern-roller ismade of three or more sections, which are independently rotatable upon amandrel, and by rotating one or more of the same, so as to bringdifferent grooves and ribs into coincidence, a large num ber ofdifferent designs may be produced. 1 designates the roller, formed inthree sections, each provided with grooves and ribs, as beforedescribed. These sections are provided with central openings formed withlongitudinal corrugations 7, which engage with correspondingcorrugations 8 of a mandrel 9. By means of these corrugations thesections will be held securely on the mandrel and prevented fromaccidentally turning thereon, but can be readily rotated when it isdesired to change the design. By this construction the character of thegraining may be readily changed, so as to accommodate the tool orimplement to varying characters of graining, which the single roller isnot capable of doing.

Having thus fully described my invention, What I claim is 1. In agraining-tool, the combination with the mandrel, of the groovedroller-sections mounted thereon, and independently rotatable on saidmandrel, substantially as and for the purpose specified.
